“SDrealtor knows much better than most of you guys. listen to what he has to say.”
sdrealtor was speaking about coastal land, whereas your blanket statement was for SAN DIEGO, and the two areas you initially referenced (4S and Del Sur) weren’t located in “coastal” areas the last time I checked.
As for East Carmel Valley, there is still quite a bit of farm land out there, which means its privately owned and could be sold to a developer if they desired.
